Cut the slot. Not pressed in.

 

Are these mixture screws available some where. online parts lists are messing with my head today? Or should/could I reuse old with new slot

 

They're available in a number of carb kits and I used to get them in sets of 4 from sirius consolidated in Canada.

You should find plenty of kits on ebay or your fellow yanquees can steer you in the right direction.

Or you could re use the old ones if they're workable.

 

When you say "snapped off" do you mean just the top slotted adjustment restricting tab?
I would cut the slot. If it comes out cleanly I might reuse if I didn't have a spare handy.

If you going to replace only use quality parts. If you use cheep parts the tips can/will snap off in the carb body. I know this from experience.

Never fails.. My Drexel has grown legs. Cut slot w hacksaw.

Not sure these carbs are saveable. We shall see how they clean up. LOL.

 

Yik.

 

Getting there.

 

Just started looking at Randakk's kit. The listing includes the idle mixture screws, but I am not seeing it in the photos attached. Can any one confirm that these are part of the package. Thanks

As this is more of a learning/practice clean, Im hoping the boy's carbs are not nearly in as bad

 

to the question in the title my advice

tequila and lots of it

drink some soak the carbs in some the proper ratio is the question

 

Randakk's kit includes the o-rings & washers for the idle screws but not the screws themselves.

Bikes made for the US market came with caps glued over the ends of the idle screws that had tabs that kept the screws from being turned very far from the way the way the factory set them (the rest of the world got unaltered screws). For most models it meant that you had to remove the float bowl to unscrew them but I seem to remember reading about some that you had to cut the tab off to properly clean the carbs. I seem to remember reading instructions for gluing the caps onto replacement screws in a manual somewhere (can't remember which bike) but I can't imagine anyone actually doing that.

Those screws look like the original ends with the caps have been broken off, although I would think that anyone who did that would cut the slots so they could adjust them.

BTW: I like to soak the brass parts of the carbs in methyl hydrate (AKA methanol) to soften any varnish. If you don't have access to an ultrasonic cleaner, Randakk recommends boiling them Old School Carb Cleaning Methods | Randakk's Blog

If you can find a compressor accessory kit like the one shown below, screw the "needle" (normally used for inflating balls &c) directly into the gun body where the nozzle normally goes and set the compressor's regulator to 10-15 PSI and you have the ideal tool for blowing out the passages inside the carb.

Sooo, is a Drexel the adult version of a Dremel?

A hacksaw with a good blade is a valuable tool indeed.

 

LOL missed that one. I meant my Dremel tool. Turns out my son lent it to a friends dad. he brought it home with him from work.
Why use muscle when you can use power.
